Answer 1

Use strpos to find the position of the first occurence of a substring and then substr to just get everything up to that position:

$pos = strpos($str, '-');
if ($pos !== false) {  // strpos returns false if there is no needle in the haystack
    $str = substr($str, 0, $pos);
}

And if you have PHP 5.3 and later, you could also use the strstr function with the third parameter set to true.

Answer 2

$pieces = explode('-', 'Hello - Bye', 2);
print $pieces[0];

Answer 3

$str = preg_replace('!-.*$!', '', 'Hello - Byte');

Answer 4

$somestring="Hello - Bye";
$array=preg_split("/\s+-\s+/",$somestring,2);
print $array[0]."\n";
